The Fail-Safe Principle

Here, I try to convince you that the BPBH also obeys the fail-safe principle (see the basic scenario) The major risk of the BPBH lies in possible blood circulation problems. I come to this later.

• locks can fail to open, although it never happened to me,
• screw links can be too tight to be released by hand, but they can always be opened with a pair of tongs,
• key rings can always be removed.

The hands, the ankles and the back chain can be released by chosing one of two locks for each. You can always remove the key rings from the chest chain. For the knee chain, you can either open the screwlink, or remove the key ring from the chain around your knees, which is always possible. At this point, you are almost free. If you are really unlucky, the screw link of one of the elbow chains block. For those, you will need to find a pair of tongs, but at this point, you will have no problem reaching them.

You need to prepare a pair of tongs, in such a way that you cannot reach them as long as you are tied. There are many ways to do this. You can for example connect yourself to something fixed, (use two locks!) and put the tongs out of reach. Alternatively, you can put them somewhere high, so that you can only reach them when you can stand.

Circulation Problems

• Make sure that the elbow chain passes twice through each ring. If you do this wrong, you are doomed.
• Make sure that it is not too cold in the room.
• Your elbows must be tied at the position where they naturally are. In this way, the force on them is as small as possible, and the force will be on the outside of the elbows. The position of your elbows is determined by the chest chain. In order to determine its right length, put your hands behind your back, as if they are tied. The chain must be just tight.
• The back chain must be pulled not too tight. Find out by experience how far you can go. Try the BPBH a couple of times without time delay.
• If you notice any problems, then lie on your side. Keep the circulation in the highest arm going by struggling. After 5 minutes change to the other side.

Permanent Traces

The BPBH leaves some permanent traces. They are fairly small, and hardly noticable. They are caused by the chestchain, when you lie on a hard background. Make sure that you lie on something that is soft enough.
